The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 2788
'A'isha (Allah be pleased with her) reported that she entered in the monthly period at Sarif, and took bath at 'Arafa (after the period was over). The messenger of Allah (may peace be upon him) said to her: Your circumambulation between al Safa and al-Marwa is enough for your Hajj and 'Umra.
